Flesch-Kincaid Analysis
Why Readability Matters for SEO
Search engines (like Google) use natural language processing to understand the complexity of your page. If you are writing an article about "How to boil an egg" but your Flesch-Kincaid score is at a College Graduate level, Google's algorithm recognizes a mismatch in user intent versus content delivery.
Additionally, complex text increases cognitive load. High cognitive load leads to users abandoning your website (bouncing). High bounce rates and low time-on-page are behavioral metrics that will actively destroy your search rankings.
The Flesch-Kincaid Reading Scale
The Flesch Reading Ease score mathematical formula analyzes the ratio of total syllables to total words, and total words to total sentences. It maps out like this:
| Score | School Level | Description |
|---|---|---|
| 90-100 | 5th Grade | Very easy to read. Easily understood by an average 11-year-old. |
| 60-70 | 8th & 9th Grade | Plain English. Easily understood by 13-15-year-olds (Target this for Web Content). |
| 30-50 | College | Difficult to read. Academic tone. |
| 0-30 | College Graduate | Very difficult to read. Scientific format, technical documentation, or legal contracts. |
How to Improve Your Score
- Shorten your sentences: If a sentence uses "and", "but", or "because", consider splitting it into two separate sentences.
- Use simpler words: Swap out multi-syllable jargon for smaller verbs and nouns (e.g. use "Use" instead of "Utilize", use "Help" instead of "Facilitate").
- Remove adverbs: Words ending in "ly" (e.g. "actually", "basically", "suddenly") clutter your text without adding meaning. Delete them.
